I must have called over 5 online places including atp, optionmotorsport and a few others and none of them have a standard t25 downpipe weld flange, atp has this flange-

but It's for a 3.0 downpipe I believe, so what am I to do in this case, Get a ruducer to a 2.5 outlet from a 3 and go from there, would that be my best bet, Im not sure If Im going to have enough room for a 3 inch downpipe, and even if I did it would be a lil overkill for the boost levels that the turbo will be running 7-psi.

This is what I used, but paid 13 bucks for it off of ebay.

I ended up cutting most of it out to increase wastegate flow. I'd go with a divorced setup if I were to do it all over again.
This is what I'm going to use when I redo my downpipe:

It all depends if you want to run a divorced setup or not. Like i said before, if I were to do it all over again, I would buy the divorced flange. If you decide to go this route, you will need this flange, a 2.25 inch ubend pipe, 1.5 inch ubend pipe and a transition pipe to what ever size exhaust you are running. OR you can buy a similar ATP flange and don't worry about the wastegate.
Again, I'm pretty sure you have a standard t25 flange. Just contact the seller to be sure.
Here are some pictures of my t25 2.5 inch dowpipe and how I customized my flange.

I wanted to use to original dump pipe, however since the turbo fits on the manifold different to that of the sr20 manifold the dump goes upward towards the hood, so It would be really hard to do anything with the stock dump, From looking at the original manifold of the sr, the turbo apparently bolted up upside down ,therfore the dump was in a different position on the hotside before hand, So basically using the cast piece would make life harder than it is so Im going to get the divorced downpipe flange and call it a day.
